1. Search the forum. You can do this from the Advanced Search Page or from our Google Custom Search, which will search the entire PKP site. If you are encountering an error, we especially recommend searching the forum for said error.

2. Check the FAQ to see if your question or error has already been resolved. Please note that this FAQ is OJS-centric, but most issues are applicable to both platforms.

3. Post a question, but please, only after trying the above two solutions. If it's a workflow or usability question you should probably post to the OCS Conference Support and Discussion subforum; if you have a development question, try the OCS Development subforum.

Try clearing your template cache manually, ie. by sshing/ftping to the server and deleting all directory contents -- you'll find it in /cache/t_compile. If that doesn't work, let us know and I'll ask a developer to take a closer look.

I'm back on the trail of this, trying to upgrade both OCS and OJS to the latest. I just ran the chmod command against my ojs cache directory, and still no joy: I get a blank screen. My cache dir looks like this:

Nope, your permissions aren't correct -- according to the listing you included above, your files are owned by the root user, and only root can write to them. You need to find out which user your web server uses to execute PHP scripts, and make sure the cache directory and all of its contents can be written by that user. It's typically "www-data" or "apache" on a Linux system using mod_php, but your configuration may vary.

Righto! Changed ownership to the Apache account and we're in bidness. (Getting a new error now when attempting the upgrade -- "A database error has occurred: Table 'ojs.copyed_assignments' doesn't exist" [and sorry, this is for my attempted OJS upgrade, not the OCS upgrade with which I initialized this thread] -- but I'm thinking there are patches I must install somewhere before performing this upgrade. Bottom line, though: Different error = Progress.)
